Doncaster Rovers could have took all three points because they were given a disputed penalty.
The Doncaster striker Paul Heffernan placed the ball on the penalty spot and the Swans keeper Dimi Konstantopoulos pulled off a great save to keep the Swans in the game.
The gaffer of the Swans said at the Keepmoat Stadium "Don't get me wrong i never thought it was a penalty but Dimi is a specialist in that department."
